Abstract

Deployment of UHF RFID technology in the industrial environment is not easy to perform because of the heterogeneity of the environment, the propagation of the high frequency radio signal, the interference, and the associated time-consuming implementation. The paper deals with deployment and evaluation of developed autonomous system for measurement of UHF RFID signals in industrial environment. Such a system allows, in defined 3D real-world locations, to obtain autonomously information about the actual Received Signal Strength Indicator of the moving RFID tag (Etalon) that is registered while investigated with each antenna of RFID reader. A corridor was chosen as an experimental area, and Received Signal Strength Indicator was evaluated by both, simulation and measurement methods. The results show a statistically significant relationship between measured and modeled Received Signal Strength Indicator in dBm at the 99% confidence level. The presented autonomous system can contribute to a more comprehensive analysis of measuring the electromagnetic field emitted by the UHF RFID antennas in various industrial environments.

工业环境下超高频RFID信号自主测量系统

在工业环境中部署超高频RFID技术并不容易，因为环境的异质性，高频无线电信号的传播，干扰，以及相关的耗时实施。本文研究了工业环境下超高频射频识别信号自主测量系统的部署与评估。这样的系统允许，在定义的3D现实世界的位置，获得有关实际接收信号强度指示器的移动RFID标签(Etalon)的自主信息，该信息是在与RFID阅读器的每个天线调查时注册的。选取一个走廊作为实验区，采用仿真和测量两种方法对接收信号强度指标进行了评价。结果表明，在99%的置信水平上，测量值和模型的接收信号强度指标(dBm)之间存在统计学上显著的关系。本文提出的自主系统有助于对各种工业环境下UHF RFID天线发射电磁场的测量进行更全面的分析。
